Abstract: By using the special vehicle in coal, the longwall equipment is carried quickly. Because of the massive use of special vehicle in coal, plenty of energy is consumed, and tail gas is released seriously, and the circumstance in coal is polluted, and the mental health of the workers is influenced. Based on the characteristics of special vehicle in coal, in the word, some energy-saving ways are analyzed and some methods to cut down the energy consumption are suggested from dynamic system and driven system and frame construction of the vehicle, which will promote the development partly about energy-saving special vehicle in coal.
